Details
These are the Shimano Dura Ace 5 pin hex bolts to connect your cranks to your chainring.
These are the new Stainless steel ones, and most importantly, they are knurled!
This means that they set into your crank holes and stay put.
They will not give you problems unlike many cheaper chainring bolts.
Ideally you would never use anything other than Sugino 75 or Shimano Dura Ace bolts.
They are etched with the Shimano name, and the set includes 10 pieces total, enough for one crank set.
These are top quality and what most pro racers in Japan are using on the track.
